          WKT is a general markup format in ASCII. It is described in detail on
          <a href="http://en.wikipedia.org/wiki/Well-known_text" target="_top">Wikipedia</a>
        </p>
<p>
          Boost Geometry supports the common formats (POINT, LINESTRING, POLYGON,
          MULTIPOINT, MULTILINESTRING, MULTIPOLYGON).
        </p>
<p>
          Because Boost.Geometry also supports Box and Segment geometries, which
          are not standard OGC geometries, there are some extensions:
